Abstract: Rotor of a rotary electric machine, comprising a body having two opposite lateral surfaces and a surface of revolution, two short-circuiting rings disposed in contact with each lateral surface of the body, and conductors disposed in slots formed on the surface of revolution of the body and each connected to the short-circuiting rings, characterised in that each conductor comprises at least one shoulder aligned with a lateral surface of the body.

Abstract: A device for making a fan or compressor for the aeronautical industry includes an annular casing with a main axis (A) and defines an internal flow duct for a gas flow along this axis. The device further includes a bladed wheel mounted inside the casing and having an axis of rotation coincident with the axis (A) of the casing. A system for retaining debris in the event of breakage of the bladed wheel has a retaining annulus mounted around the casing, which includes two radially outwardly projecting annular bosses located respectively upstream and downstream of the bladed wheel. Upstream and downstream edges of the retaining annulus are applied and attached to the bosses.
